SAP Cash Application: Why More Automation Matters for Ongoing Clearing

What Did Finance Teams Learn About Reconciliation in 2025?

SAP Cash Application: Why More Automation Matters for Ongoing Clearing

SAP cash application is still a daily problem for many finance teams. Your AR team processed yesterday’s bank receipts overnight. This morning, 35% of incoming payments still sit unmatched against customer accounts because remittance data arrived in five different formats across three email inboxes, and two customers referenced invoice numbers that do not exist in your SAP system. The outstanding items report grows longer. Staff spends another day investigating exceptions instead of chasing aged debt.

Finance teams running SAP still handle much of cash application and customer clearing manually because standard SAP does not automate the full process. When clearing is delayed, errors build up, and DSO stays higher for longer. To improve the process properly, automation needs to deal with more than the first match.

Standard SAP Handles Matching, Not Ongoing Clearing

Standard SAP provides F-28 for automatic clearing of customer open items, but it works best when payment data is clean and structured. When a customer sends a remittance advice covering multiple invoices, with partial payments or unclear allocation instructions, F-28 cannot resolve it. Finance teams export the exceptions to spreadsheets, investigate them manually, and post clearing entries later.

For many organisations, this is where SAP cash application slows down. Open item reports show inflated balances because transactions that should be cleared remain open until someone finishes the follow-up work. AR staff end up spending time reconciling payments instead of focusing on collections.

Research from the Institute of Finance & Management shows that organisations with manual cash application processes typically achieve matching rates between 60% and 80%. The rest still needs manual intervention. Every unmatched payment adds work and slows the AR cycle, which increases DSO.

Automation Must Cover Exceptions, Not Just Simple Matches

Most SAP cash application tools can deal with straightforward scenarios. The real issue is the exception work that takes up staff time. Payments may cover invoices across different periods, include deductions, or leave residual balances. In some cases, remittance data arrives separately from the payment and in a format that is hard to work with.

Organisations using in-SAP customer clearing automation report straight-through processing rates above 90% because exceptions are handled inside the system instead of being pushed into offline work. BEST’s customer clearing module processes remittances in different formats using optical character recognition, matches payments to customer accounts using configurable rules, and clears customer or bank accounts automatically within SAP.

This approach keeps SAP cash application inside SAP. There is no separate reconciliation system and no manual import of cleared items back into the platform. The clearing document posts directly to the SAP general ledger, with an audit trail showing who cleared what and when.

Ongoing Clearing Drives DSO Improvement

Days sales outstanding measures how quickly an organisation converts credit sales into cash. The formula is simple: divide accounts receivable by total credit sales, then multiply by the number of days in the period. Benchmarks vary by industry, but lower DSO usually means stronger working capital performance.

Manual SAP cash application adds days to DSO because payments can sit in suspense accounts or remain uncleared while staff investigates mismatches. A payment received on day one of the month may not clear the customer account until day five if the remittance needs manual follow-up. During that time, the receivable still appears outstanding, and the picture of customer payment behaviour becomes less accurate.

Automated clearing within SAP removes that delay. Payments can clear on the day they are received, and customer accounts update in real time. AR teams get a more accurate view of open items without waiting for manual reconciliation to finish. Organisations that automate SAP cash application and customer clearing typically report measurable DSO improvements. According to J.P. Morgan research, reducing DSO improves working capital and frees cash for operational needs.

Customer Remittances Are the Bottleneck

Most organisations receive customer remittances through several channels, including email attachments in PDF or CSV format, EDI transmissions, payment portals, and occasional paper remittance advice. Each format needs different handling, and inconsistent data quality makes matching harder.

One customer might send a single PDF listing 30 invoices with payment amounts. Another sends an email with ‘Payment for February invoices’ in the subject line and no supporting details. Some customers use an EDI 820 format that maps cleanly to SAP, but only for part of the customer base. Finance teams then spend hours extracting data, checking invoice numbers, and investigating discrepancies before they can post clearing entries.

Better SAP cash application automation removes much of this bottleneck. BEST’s customer clearing module accepts remittances through email, portal upload, or direct feed, extracts payment details using intelligent OCR, and matches them to open invoices in SAP automatically. It also handles partial payments and multi-invoice remittances without manual intervention.

The result is faster clearing and more time for collections and dispute resolution. When remittance extraction and matching happen within SAP, customer clearing becomes far less dependent on manual effort.

Audit Trails Matter for Financial Controls

Manual SAP cash application also creates control gaps. Staff export open items to spreadsheets, investigate exceptions offline, and post manual clearing entries days after receiving payment, making the audit trail harder to follow.

Auditors reviewing customer account reconciliations need evidence that payments were matched, cleared, and approved in line with documented procedures. A folder of spreadsheets with handwritten notes is not strong control evidence.

Automated clearing within SAP maintains a complete audit trail. Every clearing document shows the date, time, user ID, and supporting documentation. The remittance advice attaches directly to the clearing entry. Approval workflows can enforce segregation of duties where needed. Internal and external auditors can review the clearing history without asking for additional evidence, while management can see the clearing status in real time.

IFRS 7 and IAS 1 require organisations to disclose information about risks arising from financial instruments, including receivables, and to reconcile changes in allowances for credit risk. Accurate and auditable customer clearing records support those requirements and strengthen the control environment for accounts receivable.

In-SAP Automation Protects Your SAP Investment

Organisations running SAP have already invested heavily in the platform. Finance teams know SAP, and IT teams already support it.

Adding a separate cash application platform that extracts data, processes it externally, and posts results back into SAP increases complexity and integration risk. An in-platform approach works within the existing SAP environment using native authorisations, workflows, and audit trails. There’s no separate user management and less risk of synchronisation issues between systems. BEST’s modules are SAP-certified for Business Technology Platform and NetWeaver and compatible with RISE with SAP.

This also matters for S/4HANA migrations. Organisations moving to S/4HANA can implement in-SAP clearing automation during the migration instead of adding external tools later. The overall architecture stays cleaner, and the SAP investment goes further.

Automation Frees Capacity for Higher-Value Work

Finance teams under pressure to close faster and do more with the same headcount can’t afford to spend days manually clearing customer payments.

When SAP cash application and customer clearing run automatically within SAP, AR staff spend less time on administrative work and more time on overdue balances and disputes, giving teams more room to act earlier and improve cash collection performance.

Automated customer clearing also helps remove a common AR bottleneck during close. Payments clear on the day they are received, and the AR sub-ledger is easier to balance back to the GL.

If your AR team still spends days each month manually clearing customer payments, or your open item reports stay inflated because clearing lags behind cash receipts, in-SAP automation gives you a direct way to improve the process.
